Ballistic arcs with quadratic air resistance --- asymmetric trajectories, terminal velocity approach
Standard analysis sees: smooth / autocorrelated; long-range memory (persistent); low-complexity (predictable, not noise-like); time-irreversible (sharp rises, slow decay); volatility-clustering (bursty). The atlas finds no named structure, but the source is distinctively extreme on Visibility Graph:avg_clustering_coeff (-5.4z) — beyond what the standard bank predicts for it. It sits beside Chua's Circuit in the atlas (standard-bank rank 61) — a neighbor conventional features miss.
